The switch state of right eyeglass.Specifically, when generation module receives synchronization signal embedded instructions, then illustrate to regard 3D at this time
Frequency obtains video data according to the synchronization signal embedded instructions according to the operation for carrying out embedded synchronization signal.
Step S20, the generation module encode each frame of the video data based on default embedded rule, obtain
To the frame of embedded synchronization signal；
In the present embodiment, active 3D is mainly to realize 3D effect, frame sequence by improving the refresh rate of picture
Before and after frames correspond to two groups of pictures of left eye and right eye, continuous interlaced display comes out, while Synchronization Control shutter type 3 D spectacles
Left and right eyeglass switch, enables left and right eyes to see respective picture at the time of correct, spectators is allowed to see the stereoscopic effect of 3D.
In short, in the present invention, 3D video data includes two kinds of frame, it is left-eye image frame and eye image frame, difference respectively
The left eyeglass and right eyeglass of corresponding 3D glasses need to open 3D glasses that is, when the screen of display end shows left-eye image frame
Left eyeglass, close right eyeglass；Similarly, when the screen of display end shows eye image frame, need to open the right side of 3D glasses
Eyeglass closes left eyeglass.
Therefore, 3D glasses need precisely synchronous with the picture of viewing, can be by left and right synchronization signal built in each frame
Mark, the equipment through display end decodes the synchronous mark in left and right, and regeneration synchronous control signal is sent to 3D glasses, 3D
Mirror controls the switch state of left eyeglass and right eyeglass according to synchronous control signal.
Specifically, step S20 includes:
Step S21, the generation module are based on first group of preset value and encode to left-eye image frame, obtain embedded synchronization
The left-eye image frame of signal；
In the present embodiment, in the mark of left and right synchronization signal built in each frame, that is, to some or all of frame picture
Vegetarian refreshments is encoded, and in recovery module by decoding to these pixels after being encoded, can be recognized accurately and to be received
Frame is left-eye image frame or eye image frame.
Specifically, step S21 includes:
Step a, the generation module are based on the first coding rule, determine the first pixel to be encoded in left-eye image frame
Point；
In the present embodiment, a frame image includes the pixel of preset quantity, and specific quantity is related with the resolution ratio of image,
Such as the format standard of 720P (Progressive, line by line) digital TV in high resolution, 720P are that one kind reaches under progressive scan
The display format of 1280 × 720 resolution ratio, including 780,000 or so dynamic pixel.Each pixel can use RGB or YUV table
Show, wherein RGB is the color for representing three channels of red, green, blue, and " Y " indicates brightness (Luminance or Luma), also
It is grayscale value, that " U " and " V " is indicated is then coloration (Chrominance or Chroma), and effect is description colors of image and saturation
Degree, the color for specified pixel.For convenience, it is illustrated with the RGB of pixel.
Specifically, pixel all in a frame image is all supported to encode, to be encoded to determine according to specific circumstances
Pixel.Pixel is encoded, the rgb value after coding, can be had any different with former rgb value, so, when formulating coding rule, need
Consider code efficiency and image effect, pixel all in frame image can be encoded, realizes embedded synchronization signal
Mark, part pixel can also be determined according to coding rule, is then encoded to these pixels, and then is realized embedded same
Walk signal identification.
Step b, the generation module are based on first group of preset value and encode to first pixel, obtain institute
State the left-eye image frame of embedded synchronization signal.
In the present embodiment, it after determining pixel to be encoded according to the first coding rule, is treated using first group of preset value
Encoded pixels point is encoded, and the left-eye image frame of the embedded synchronization signal is obtained.Because the rgb value of pixel includes 3
Channel, each channel can be carried out encoding, these preset values are for the value of RGB dedicated tunnel to be become odd number or even number.
According to pre-set coding rule, the dedicated tunnel for treating encoded pixels point respectively is encoded.As long as it should be noted that
Left-eye image frame is different with the coding rule of eye image frame, i.e., built-in left and right synchronization signal identifies different, in this way reduction mould
Root tuber is according to the synchronization signal mark recognized, so that it may determine that present frame is left-eye image frame or eye image frame.
For example, being encoded to the channel G of a pixel of left-eye image frame, the channel G of the pixel after coding
For odd number, at this point, first group of preset value is to contain 2 values: 0xFE and 0x01 encodes the channel G, i.e. G=(G&
0xFE) | the lowest order of 0x01, the G after coding are 1, i.e., the channel G is odd number；Similarly, if it is desired to making the G of the pixel after coding logical
Road is even number, and first group of preset value is to contain 1 value: 0xFE encodes the channel G, i.e. G=(G&0xFE), after coding
The lowest order of G be 0, i.e., the channel G is even number.From numerically calculating, the value more probability in a channel of a pixel are as follows: 1/
256*256*256=0.000000059 can be ignored, with the naked eye watching, even more not for whole frame picture
Have any difference.
Step S22, the generation module are based on second group of preset value and encode to eye image frame, obtain embedded synchronization
The eye image frame of signal.
In the present embodiment, in the mark of left and right synchronization signal built in each frame, that is, to some or all of frame picture
Vegetarian refreshments is encoded, in recovery module by being decoded to these pixels after being encoded, so that it may be recognized accurately, connect
The frame received is left-eye image frame or eye image frame.
Specifically, step S22 includes:
Step c, the generation module are based on the second coding rule, determine the second pixel to be encoded in eye image frame
Point；
In the present embodiment, a frame image includes the pixel of preset quantity, and all pixels are all supported in a frame image
Coding determines pixel to be encoded according to specific circumstances, that is, generation module determines right according to the second coding rule
Second pixel to be encoded in eye picture frame.
It should be noted that pixel is encoded, the rgb value after coding can have any different with former rgb value, so, it is formulating
It when coding rule, needs to consider code efficiency and image effect, pixel all in frame image can be encoded, realized
Embedded synchronization signal mark, part pixel can also be determined according to coding rule, is then encoded to these pixels, into
And realize embedded synchronization signal mark.
Step d, the generation module are based on second group of preset value and encode to second pixel, obtain institute
State the eye image frame of embedded synchronization signal.
In the present embodiment, it after determining pixel to be encoded according to the second coding rule, is treated using second group of preset value
Encoded pixels point is encoded, and the left-eye image frame of the embedded synchronization signal is obtained.Because the rgb value of pixel includes 3
Channel, each channel can be carried out encoding, these preset values are for the value of RGB dedicated tunnel to be become odd number or even number.
According to pre-set coding rule, the dedicated tunnel for treating encoded pixels point respectively is encoded.As long as it should be noted that
Left-eye image frame is different with the coding rule of eye image frame, and built-in left and right synchronization signal identifies different, such recovery module
According to the synchronization signal mark recognized, so that it may determine that present frame is left-eye image frame or eye image frame.
For example, being encoded to the channel G of a pixel of left-eye image frame, the channel G of the pixel after coding
For odd number, at this point, first group of preset value is to contain 2 values: 0xFE and 0x01 encodes the channel G, i.e. G=(G&
0xFE) | the lowest order of 0x01, the G after coding are 1, i.e., the channel G is odd number；Similarly, if it is desired to making the G of the pixel after coding logical
Road is even number, and first group of preset value is to contain 1 value: 0xFE encodes the channel G, i.e. G=(G&0xFE), after coding
The lowest order of G be 0, i.e., the channel G is even number.From numerically calculating, the value more probability in a channel of one pixel are as follows: 1/
256*256*256=0.000000059 for whole frame picture, so that it may ignore, with the naked eye watch, even more will not
There is any difference.Further, if left-eye image frame and eye image frame are compiled to the channel G of the first pixel
Code, then can allow the channel G of left-eye image frame is odd number, and the channel G of eye image frame is even number.
Step S30, the generation module successively send the frame of each embedded synchronization signal to the recovery module, so that institute
It states recovery module and generates synchronous control signal.
In the present embodiment, generation module carries out left-eye image frame according to first group of preset value and the first coding rule
Coding realizes built-in left synchronization signal mark；According to second group of preset value and the second coding rule to left-eye image frame into
Row coding realizes built-in right synchronization signal mark.It should be noted that each frame in video data is successively to carry out respectively
Coding, i.e., generation module encodes present frame, and then by the frame after coding, that is, the frame of embedded synchronization signal is sent
To recovery module, so that recovery module generates the synchronous control signal of control 3D glasses, the picture essence of 3D glasses and viewing is realized
It is plesiochronous.
The method of data synchronization that the present embodiment proposes, by receiving synchronization signal embedded instructions in the generation module
When, video data is obtained based on the synchronization signal embedded instructions, then the generation module is based on default embedded rule to institute
The each frame for stating video data is encoded, and the frame of embedded synchronization signal is obtained, and the following generation module is successively sent respectively
The frame of a embedded synchronization signal is to the recovery module, so that the recovery module generates synchronous control signal.By in video
The mark of Data Encapsulation or so synchronization signal, the equipment through display end decode the synchronous mark in left and right, regenerate synchronously control
Signal is sent to 3D glasses, and 3D glasses control the switch state of left eyeglass and right eyeglass according to synchronous control signal, and then realize
3D glasses and the picture of viewing are precisely synchronous, while the present invention can be realized based on existing 3D system, be set without newly-increased additional
It is standby.
The second embodiment of method of data synchronization of the present invention is proposed, in the present embodiment referring to Fig. 3 based on first embodiment
In, after step S30, further includes:
Step S40, the recovery module is when receiving the frame that the generation module is sent, based on default decoding data pair
The frame received is decoded, and generates synchronous control signal based on decoded data；
In the present embodiment, it when recovery module receives the frame of generation module transmission, needs to judge to be currently received
Frame is left-eye image frame or eye image frame, therefore is decoded according to default decoding data to the frame received, obtains and synchronizes
Then signal identification generates synchronous control signal according further to decoded frame.
Specifically, step S40 includes:
Step S41, the recovery module are based on the default decoding data, are decoded, are solved to the frame received
Data after code；
In the present embodiment, generation module is encoded by treating the dedicated tunnel of encoded pixels point, the rule of coding
It is then exactly to allow the lowest order in channel for 0 (even number) or 1 (odd number), therefore default decoding data can be 0x01, identify using 0x01
Channel value is odd number or even number out.For example, if left-eye image frame and eye image frame are all the channels G to the first pixel
It is encoded, the channel G of left-eye image frame is odd number, and the channel G of eye image frame is even number, then recovery module reads present frame
The G channel value of first pixel, when G channel value is odd number, i.e. when G&0x01==0x01, which is left-eye image frame；Work as G
When channel value is even number, i.e. when G&0x01==0x00, which is eye image frame.
Step S42, the recovery module determine whether the decoded data meet the first decision rule；
Step S43, when determining that the decoded data meet the first decision rule, the recovery module generates left same
Step control signal；
In the present embodiment, the first decision rule is related to the first coding rule, and generation module is according to the first coding rule
Pixel to be encoded has been determined, then the first decision rule is just decoded these pixels to be encoded, the data after being decrypted.
First decision rule will also provide the rule of left synchronization signal mark, which channel that generation module treats encoded pixels carries out
It encodes, the channel value is odd number or even number after coding, these require to be embodied in the first decision rule.For example, generating mould
Block all encodes the first pixel of left-eye image frame and the channel R of the second pixel, the R of the two pixels after coding
Channel value is odd number, then it is odd number that the first decision rule, which is exactly the R channel value of the first pixel and the second pixel,.
Specifically, recovery module is based on default decoding data, is decoded to the frame received, obtains decoded number
According to then further determining that whether decoded data meet the first decision rule, first sentence if decoded data meet
Set pattern then, then illustrates that the frame being currently received is left-eye image frame, then generates left synchronous control signal.
Step S44, the recovery module determine whether the decoded data meet the second decision rule；
Step S45, when determining that the decoded data meet the second decision rule, the recovery module generates right same
Step control signal.
In the present embodiment, the second decision rule is related to the second coding rule, and generation module is according to the second coding rule
Determine pixel to be encoded, then the second decision rule is just decoded these pixels to be encoded, the data after being decrypted.The
Two decision rules will also provide the rule of right synchronization signal mark, which channel that generation module treats encoded pixels is compiled
Yard, the channel value is odd number or even number after coding, these require to be embodied in the second decision rule.For example, generation module
The channel R of the first pixel and the second pixel to eye image frame is all encoded, and the R of the two pixels is logical after coding
Road value is even number, then it is even number that the second decision rule, which is exactly the R channel value of the first pixel and the second pixel,.
Specifically, recovery module is based on default decoding data, is decoded to the frame received, obtains decoded number
According to then further determining that whether decoded data meet the second decision rule, second sentence if decoded data meet
Set pattern then, then illustrates that the frame being currently received is eye image frame, then generates right synchronous control signal.
Step S50, the recovery module send the synchronous control signal to the 3D glasses.
In the present embodiment, synchronization signal is exactly to the machinery equipment offer same time reference for needing synchronization process information
Signal, such as all television relays, mobile communication etc., synchronization signal can be a switching signal, be also possible to one it is continuous
Pulse.In the present invention, synchronous control signal is exactly to be used to that 3D glasses to be notified when to open eyeglass switch and need to keep more
For a long time.Specifically, recovery module sends synchronous control signal to 3D glasses in real time, and the eyeglass for controlling 3D glasses switchs shape
State.
Further, in one embodiment, after step S50 further include: the 3D glasses are receiving the synchronous control
When signal processed, the left eyeglass of the 3D glasses and the switch state of right eyeglass are controlled based on the synchronous control signal.
In the present embodiment, synchronous control signal is switched for controlling the eyeglass of 3D glasses, and synchronous control signal includes
Left synchronous control signal and right synchronous control signal then control 3D glasses when 3D glasses receive left synchronous control signal
Left eyeglass is opened, and right eyeglass is closed；, when 3D glasses receive right synchronous control signal, then the right eyeglass for controlling 3D glasses is beaten
It opens, left eyeglass is closed.
The method of data synchronization that the present embodiment proposes is receiving what the generation module was sent by the recovery module
When frame, the frame received is decoded based on default decoding data, generates synchronous control signal based on decoded data, and
